LUBRICATING DEVICE.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed November 14, 1905. Serial No. 287,230.

T0 at whom it may concern:

Be it known that I, WILLIAM H. OCoiv- NOR, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oiling or Lubricating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

The objects of this invention are to secure a uniform pressure of oil or other lubricating fluid, whereby the fluid will be fed uniformly to the wearing parts of the machine; to thus secure a more regular and constant supply of lubricant at the bearings of said parts to enable the lubricant tobe fed from the receptacle therefor until the same is practically eX- hausted without any necessity of premature replenishing; to reduce the labor of replenishing the oil cups or receptacles; to facilitate the work of replenishing the lubricant; to economize the use of oil because of the more constant and regular normal supply of a minimum quantity, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved lubricating device and in the arrangements and combinations and parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the figures, Figure 1 is a central vertical sectionof the improved lubricating device, and Fig. 2 is a plan of the lower endof the lubricant-reservoir.

Insaid drawings, 5 indicates the body of the lubricant-receptacle, which is preferably of glass and is closed at the top to form a chamber 51, in which a partial vacuum may be formed above the supply of lubricant. Below the body 5 the receptacle is reduced and made cylindrical as at 6, to fit more or less closely into the metallic cup hereinafter referred to, and below the cylindrical part 6 the said receptacle is further reduced, as at 7, preferably on inwardly-curved lines, as shown, the reduced parts being hollow to form a passage 8 for the downfiowing lubricant. The cylindrical part 6 is not so close in its relation to the inner wall of the cup as to prevent an air-passage therebetween. Indeed, I prefer to formin the outer side wall of said cylindrical portion a groove or passage 9 for venting the annular chamber 1.0, formed around the smallest part 7 of the neck. The oil-cup 1 1 is preferably of metal, such as brass, and is of greater depth than the length of the neck is provided with a valved feed extension 12-,

-of which 13 indicates the spigot, adapted to be turned by a finger piece or portion 14, the said spigotgoverning the flow of lubricant through the exit-passage 16 to the parts to be lubricated.

The device may be attached to the machinery to be lubricated by the threaded nipple 15 or by any of the means common in the art, and the valve 13 or other means for governing the flow from the cup 11 may be varied as may be found best.

In operating the device the lubricant is filled into the body 5, the open neck being turned u to receive the liquid. The cup 11 is then p aced over the neck and the whole inverted to the position shown in Fig. 1, so that a portion of the liquid flows down into said cup, a partial vacuum being formed in the upper part of the body portion. This vacuum serves to prevent a further downflow from the large storage-chamber in the body, excepting as air 'is permitted to flow up through the neck-passage 8 as the liquid in the chamber 17 of the cu is fed down from said chamber 17 throug the passage 16 to the parts to be lubricated. The airpassage 9 and annular chamber 10, being open to normal air-pressure, permit a free gravitation of the liquid in the oil-cup, and as this column of liquid remains constant until the supply of oil is nearly exhausted, being fed from above as air is permitted to enter under the edge of part 7, the pressure is uniform and but of a small degree, so that the oil is not at first flushed upon the bearings and afterward fed in lessening quantities, but is fed regularly, as above indicated.

Having thus described the invention, what I claim as new is An improved oiling device, comprising a reservoir closed at its top and having a reduced lower end with an exit-passage for the lubricant, said reservoir having a reduced cylindricallower part and an inwardly-turned lower extremity adapted in conjunction with ln testimony that I claim the foregoing I the cup to form an annular chamber around about said extremity, and a valved cup adapted to receive said cylindrical part at its upper end and form a chamber at its lower part for a limited supply of lubricant, provision being made for lntroduction of atmospheric pressure into the cup.
